- Documentation for JoyStick 1.2; A multi-purpose joystick
- interface for the Amiga. This software IS NOT public-domain, or
- redistributable; see restrictions below.
-
-
- OVERVIEW
-
- JoyStick allows a joystick connected to the Amiga's gameport to
- be used in conjunction with the mouse and keyboard. JoyStick can
- simulate the normal mouse movement actions of positioning,
- clicking, dragging, and accessing menus. It can also be
- configured to send character strings to the computer as though
- they were entered from the keyboard.
-
-
- COMMAND LINE
-
- JoyStick [-w] [-?] [-q] [-m] [-i#] [-t#]
- [Quit|Mouse] | [Increment|Threshold #] | [Menu [TRUE]] |
- [Mode5|Mode8 [filename]]
-
- Flags: Any flags must be prefaced by '-' and located before the
- optional command. Flags are only interpreted by the 'local'
- JoyStick executable; They will not be sent to an already-running
- copy. Thus, they are most useful when starting JoyStick from a
- CLI. Flags do not toggle.
-
- -w: Suppress banner window. Upon startup JoyStick opens a
- banner window on the Workbench screen showing the copyright and
- author messages. After a preset time, the window is either
- resized to occupy only the screen titlebar, or is closed
- completely (if the -w flag is specified). An executing JoyStick
- program w/o a window may be terminated by using the 'Quit'
- command, or by sending the appropriate ARexx message (See ARexx
- interface section below).
-
- -q: Quiet mode. JoyStick will not output any information to
- CLI. This will only be overridden by a trailing -? parameter.
-
- -m: Menu action setting. JoyStick will only simulate an
- Right-Mouse-Button (RMB) action if the pointer is located at the
- top of the screen (See Mouse command below). If this flag is
- set, the currently active window must have a menu attached or the
- menu action will be ignored.
-
- -i: Increment specification. This flag allows command line
- control similar to the 'Increment' command (See below).
-
- -t: Threshold specification. This flag allows command line
- control similar to the 'Threshold' command (See below).
-
- -?: This displays a list of all flags and commands recognized
- by JoyStick.
-
-
- COMMANDS
-
- Only one command is valid per invocation, and it must be located
- after any specified flag(s).
-
- Quit: Forces an executing JoyStick program to close down. This
- is exactly the same as closing the default Workbench window.
-
- Mouse: JoyStick defaults to 'Mouse' operation. In this mode,
- actions performed on the attached joystick are sent to the Amiga
- as though the analogous actions were performed on the system's
- mouse. Cursor positioning is performed by positioning the
- joystick's handle in one of its eight positions. Clicking is
- performed by depressing the joystick's button.
-
- All activations of the joystick's button are translated into
- left-mouse-button actions UNLESS the cursor is at the very top of
- the active screen. Only then are menu button actions simulated.
- The presence/absence of menus for the currently selected window
- may be used to determine if an RMB action is performed. This may
- be controlled by the -m flag and/or the 'Menu' command.
-
- The speed and acceleration of the pointer may be controlled by
- the Increment and Threshold commands described below.
-
- Threshold: The required parameter (t) allows control over the
- number of moves before the pointer accelerates. After 2^t moves
- the pointer will start moving twice as far each time. The
- maximum number of these accelerations may be controlled by the
- Increment command.
-
- Increment: The required parameter specifies the maximum number
- of accelerations. When this value is reached, the speed of the
- pointer will remain constant until the user releases the stick.
-
- Menu: This command allows setting the restrictions on JoyStick's
- generation of RMB actions. If a 'TRUE' parameter is specified,
- RMB actions will occur only when the currently active window has
- an attached menu. Otherwise, RMB actions are performed whenever
- the pointer is at the top of the screen. This command duplicates
- the actions of the -m flag.
-
- Mode5: When in this mode, keyboard actions are simulated while
- leaving the computer's pointer unaffected. When the joystick's
- button is depressed, the state of the handle is checked, and one
- of five (5) character sequences is initiated. If the handle is
- centered, a simple 'Click' is reported, otherwise, one of the
- actions 'Up', 'Down', 'Left' or 'Right' is selected.
-
- JoyStick does not contain the default strings for these settings.
- When it is switched into 'Mode5', it attempts to read the file
- 'S:JoyStick.KeyStrings'. This is simply an ASCII string file
- which may be edited to contain any strings desired. (See 'String
- files' below).
-
- The default file is scanned unless the name of a specific string
- file is specified, similar to:
-
- JoyStick Mode5 Work:TestStrings
-
- This will force the reading of the 'Work:TestStrings' instead of
- the default. This filename may not contain spaces.
-
- Mode8: This mode operates similar to Mode5 above, but generates
- more strings. To do this, activation is sensed when the joystick
- handle is moved into one of the four primary positions. When
- this happens the state of the button is checked, and if
- depressed simulates a SHIFT action.
-
- Mode8 will not generate a string if one of the diagonal settings
- is selected, but will wait until the handle is moved into one of
- the four primary positions.
-
-
- STRING FILES
-
- JoyStick uses files containing ASCII string specifications of the
- command character sequences. One line is used for each sequence,
- including all characters up to a carriage-return. Characters not
- easily entered from the keyboard (<ENTER>, for example) may be
- specified by entering their ASCII-numeric codes inside '\'
- characters. These numbers may be specified in decimal, hex, or
- binary. For example, a sequence to generate a directory listing
- could be specified as:
-
- 1. using a decimal number:
- dir\13\
- 2. using a hexidecimal number with a trailing 'X' or 'x':
- dir\dx\
- 3. or using a binary number with a trailing 'B' or 'b':
- dir\01101b\
-
- When the '\' character is to be used in the command, specify
- with two adjacent slashes, ie: '\\'.
-
- The file currently may contain up to nine (9) strings. The table
- below shows how the strings are interpreted, and which modes use
- each of the stings. Any blank lines are simply ignored.
-
- String # Interpretation Mode5 Mode8
-
- ---------------------------------------------------------
- 1 Click X
- 2 Up X X
- 3 Down X X
- 4 Left X X
- 5 Right X X
- 6 Shift Up X
- 7 Shift Down X
- 8 Shift Left X
- 9 Shift Right X
-
-
- ARexx interface. (ARexx IS NOT needed to run JoyStick.)
- After JoyStick is operational, all further communication with it
- is done through ARexx messages; Subsequent command line
- activations send messages to the already-running program
- instructing it to change modes, quit, etc.
-
- Any program with an ARexx port may control a running JoyStick in
- the same manner. The port named 'JoyStick' currently accepts Rexx
- string messages of these types:
-
- Quit
- Mouse
- Increment Number
- Threshold Number
- Menu State
- Mode5 Filename
- Mode8 Filename
-
- Number is required, and must be between 1 and 9 inclusive.
- State is optional, and interpreted as FALSE unless the first
- character is 't' or 'T'.
- Filename is optional, and may not contain spaces.
-
-
- WORKBENCH OPERATION
-
- JoyStick may be started or stopped by double-clicking on its
- icon. If JoyStick is already running, it will be terminated by
- an activation from Workbench (as well as by using the 'Quit'
- command from CLI or ARexx). Upon startup from Workbench, the
- ToolTypes of the icon are checked for the following settings.
-
- WINDOW=False Suppresses the screen-title window after startup.
- Default: TRUE
-
- MENU=[TRUE] This restricts RMB actions to windows with menus.
- Default: FALSE
-
- INCREMENT=# The number specified is used as the increment
- setting. See usage and default discussion above.
-
- THRESHOLD=# The number specified is used as the threshold
- setting. See usage and default discussion above.
-
- MODE5=filename JoyStick is started in MODE5 mode, and the
- specified control file is loaded.
-
- MODE8=filename JoyStick is started in MODE8 mode, and the
- specified control file is loaded.
-
-
- RESTRICTIONS
-
- JoyStick IS NOT public-domain.
-
- This program has been licenced to Commodore. It may not be
- distributed by other parties without the expressed consent of
- Commodore.
